United States Patent 3,288,026 BOWLING SCORE SHEET FILM POSITIONING ANDHOLDING DEVICE Stanley E. Condon, Plymouth, Ohio, assignor to AmericanMachine & Foundry Company, a corporation of New Jersey Filed Aug. 27,1964, Ser. No. 392,562 9 Claims. (CI. 88-24) This invention relatesgenerally to a device for positioning and holding a bowling score sheeton the transparent or translucent writing table of a conventionalbowling score projector. More particularly, this invention relates tosuch a score sheet holding device for use especially during team play,which includes a magazine for storing a supply of unused score sheetsand which is relatively easy to remove from and replace on the writingtable with the score sheet in proper aligned position with theprojecting system of the score projector.

At present, with conventional bowling score projectors, it is commonpractice to utilize a heavy-gauge, costly, transparent printed sheethaving from one to six scoring areas thereon to provide for temporarilyrecording a bowling score which is to be displayed by a bowling scoreprojector so that the various scores are visible to an audience watchingthe bowlers. Due to the cost of such heavy-gauge printed sheet, it iscommon practice to make a record of the score and then erase themarkings from the heavy-gauge printed sheet so that the sheet can bereused. Since there is frequently no reproducing device available at thebowling alley for making a permanent record from the heavy-gauge scoresheet, it is necessary to manually transfer the scores for variousframes to a separate, inexpensive sheet after play is completed. Theinconvenience of transferring the scores and the cost of erasing andhandling such reusable sheets has been found to be very undesirable.

Another undesirable aspect of such heavy-gauge, reusable sheets is theremoval and replacement of the sheets after each team game. Theheavy-gauge reusable sheets are only used during team play. When thelanes where the bowling score projector is located are used by otherbowlers, an inexpensive score sheet is provided. Hence, there isnormally no provision on the writing table of the projector for properlyaligning the heavy-gauge sheets relative to the projecting system of theprojector. Therefore, each time a heavy-gauge sheet is replaced, duringteam play, it is necessary for the scorekeeper to look at the projectedimage to determine that the sheet is properly positioned to display thescore for view by the audience. If the sheet is not properly positioned,the game is frequently delayed, with corresponding inconvenience to theteam players, 'and increased expense to the bowling alley proprietor,since the bowlers pay on a per-game basis.

This invention alleviates, during team play, the problems previouslyencountered with heavy-gauge, reusable printed score sheets by providinga score sheet holder and positioning device which includes a magazinefor storing a plurality of score sheets in the form of thin, transparentfilm. In the preferred embodiment, yet to be disclosed, the frame of thescore sheet holder functions to accurately position the score sheet, orscore sheets, as the case may be, relative to the projecting system ofthe score projectorwhen the score sheet holder is mounted on the writingtable in a predetermined position. A magazine for storing unused scoresheet film is secured to the frame. Hence, when team play commences itis merely necessary for the proprietor of the bowling alley to providethe teams with a holder which can be easily carried to and mounted onthe writing table of the projector. After team play is completed, thescore sheet holder is returned to the proprietor and normal, inexpensivescore sheets can again be used by non-team players on the writing tableof the projector, since it is not necessary to project the scores ofnon-team players.

In accordance with one embodiment of this invention, the score sheetitself is a clear, transparent sheet of film material with no printingthereon to indicate the various player lines or frames. In thisinstance, a printed score grid is connected to the frame of the scoresheet holder and it is merely necessary to pull the clear film intoposition over the printed score grid. In a variation of this concept,the score grid may be permanently associated with the transparent ortranslucent writing table of the projector, such as by etching orotherwise permanently affixing the score grid to the writing table. Thescore sheet grid may also be directly printed onto the score sheet filmin the conventional manner.

Another distinct advantage of the score sheet, score sheet holder andframe of this invention is the disposition of score sheets in side byside relation on the same scoring table to permit one scorekeeper torecord the scores of two opposing teams.

Accordingly, an object of this invention is to provide a bowling scoresheet holder which is effective to accurately position a score sheetfilm in proper aligned regis tration with the projecting system of abowling score projector.

Another object of this invention is a bowling score sheet holder whichincludes a magazine for storing unused score sheet film.

Another object is a holder for score sheet film which maintains thescoring surface of the film exposed for writing thereon by a scorekeeper, and in which the positioning frame of the holder is secured to ascore sheet magazine to provide a one-piece unit that is easily removedand replaced. I

A further object of this invention is a holder for score sheet film in acontinuous strip, which film is manually fed from a magazine to properposition on the writing table of a bowling score projector and whichincludes a device for severing used score sheet film from the unusedfilm.

Yet another object is a combined bowling score film holder and magazinewith its various parts so arranged that the score sheets of opposingteams are maintained in side-by-side relation on top of the same writingtable of the score projector to permit one scorekeeper to record thescores of two opposing teams, and in which the holder is positioned inthe normal ashtray slots of the writing table of the score projector andthe ashtrays themselves function to secure the holder to the scoreprojector table.

Another and further object is a combined film holder and magaizne whichincludes a securing device to hold score sheet film fed from themagazine in a predetermined position and against accidental movement.

A still further object is a bowling score film holder and magazine whichis inexpensive to manufacture, easy to use, and provides for the use ofrelatively inexpensive transparent film for recording a permanent recordof the team games 'as played.

In order that the manner in which the foregoing and other objects areattained in accordance with the invention can be understood in detail,particularly advantageous embodiments of the invention will be describedwith reference to the accompanying drawings, which form a part of thisspecification, and wherein:

FIGURE 1 shows a bowling score projector system on which the score sheetholder of this invention is mounted in use;

FIGURE 2 is a perspective view of the score sheet FIGURE 8 is a partialview in plan of a transparent V preprinted score sheet film in positionin the holder;

FIGURE 9 is a view similar to FIGURE 8 with a transparent unprintedscore sheet film in position in the holder, the score sheet grid beingpermanently associated with the glass of the projector table;

FIGURE 10 is a view similar to FIGURE 8 with a transparent unprintedscore sheet in position in the holder, the score sheet grid being on atransparent sheet disposed between the score sheet film and theprojector table glass; and

FIGURE 11 is an enlarged sectional view looking along lines 11-11 ofFIGURE 10.

Referring now to the drawings in detail, and particularly to FIGURES 1and 2, a score sheet holder and positioning device 1, in accordance withthis invention, is shown mounted on the writing table 2 of a bowlingalley scoring projector 3.

Scoring projector 3 is of the general type disclosed in US. Patent2,330,799 Coker and, as best seen in FIGURE 1, includes a pedestal 4 onwhich writing table 2 is mounted, and a housing 5 spaced above writingtable 2 and supported by a suitable bracket 6, the housing 5 containinga suitable mirror and lens system to project the image written uponscore sheet film 7 disposed on table 2 onto a screen 7 due to the actionof light projected upwardly through the score sheet from -a projectinglamp within pedestal .4.

As shown in FIGURE 2, Writing table 2 of the scoring projector includesa transparent or translucent glass plate 8 disposed between portions 9and 10' which may be of wood covered with a durable material such asFormica.

As best seen in FIGURES 3 and 4, score sheet holder 1 includes a frame11,.and a score sheet film magazine 12 connected to one side of theframe and disposed below the plane of the frame.

Frace 11 includes a body member 13 of thin sheet metal, an elongatededge strip 14 also of sheet metal and secured to the upper face of thebody portion adjacent its top edge as by welding, and a spring biasedscore sheet film retainer 15 disposed midway of the body portion andwhich functions to prevent movement of the score film 7 by pressing sameagainst a plate secured to the frame, as shown in FIGURE 6. At one sideof the score sheet retainer 15, body portion 13 is cut away to providean elongated, generally rectangular opening 16. A similar opening 17 isprovided in body portion 13 on the other side of score sheet retainer15.

Although each of openings 16 and 17 appears to be generally rectangularas seen in FIGURES 3 and 8-10 a careful observation shows that the innerside edges 18 of openings 16, 17 are somewhat longer than the outer sideedges 19 of these openings. Due to this difference in length the bottomedges 20 of each opening slope upwardly in a direction away from thecenter of score sheet holder 1. Such convergence of bottom edges 20 in adirection toward the side edges or writing table 2 serves two functions.The first is that such an arrangermentis more aesthetically pleasingthan if openings 16, 17 are truly rectangular. The second is that makingthe openings converge in a direction toward the edges of the table tendsto compensate for the optical and projecting system of scoring projector3. Otherwise, the image projected onto screen 7' would not be trulyrectangular, but would be shorter at the center and longer at each sideedge of the image unless of course, a complicated optical system isincorporated in the scoring projector.

to compensate for the difference in distance between the center andsides of the various portions of each score sheet from the lens systemin housing 5. As will subsequently be explained in detail, the variousscore sheet grids of FIGURES 8-10 have laterally extending player lineswhich also converge slightly in a direction toward the side edges ofwriting table 2.

, Sheet metal of body portion 13 is bent downwardly at the left handside thereof as viewed in FIGURES 3 and 4 to provide a leg 21, and isthen bent outwardly to provide a leg 22 disposed below and offset to oneside of body portion 13. The bend 23 between body portion 13 and leg 21is at a slight angle with the side edges of body portion 13. Bend 24between legs 21 and 22 is so formed that the plane of leg 22 is disposedat an acute angle to the plane of body portion 13, and these planesintersect in a direction toward an observer looking at the embodimentofFIGURE 4.

Leg 22 provides a mounting support for magazine 12.

Magazine 12 includes a first end plate 25 and a second erally centrallythereof to receive the reduced diameter ends of a shaft 29 that extendsbetween the end plates.

The thin material of the end plates provides sufiicient elasticity topermit removing the shaft to renew a roll 30 of score sheet film 7.Mounted in suitable openings offset toward one side of end plates 25, 26in a direction toward frame 11 is a guide roller 31 which functions toguide film 7 during feeding into frame 11.

As best seen in FIGURES 4 and 5, the side edges of body portion 13 ofthe holder are turned downwardly and then inwardly to provide a pair ofinwardly facing elongated parallel guide slots 32 and 33, the guideslots functioning to receive the edges of the score sheet film to guidethe film while feeding the film into position relative to the projectingsystem of scoring projector.

The upper edge of each end plate has a flange Each end plate Secured toa center web 34 of body portion 13, as by welding, are a pair of spacedapart one-half hinge mem-' bers 35. A coacting half hinge member 36 ismounted on the upwardly extending portion 37 of score sheet fihnretainer 15. Suitable torsion springs 38 disposed on a pin 39 whichconnects the hinge half members together provide the necessary bias tonormally press a resilient rubber pad 40 downwardly against score film7. Since pad 40 is mountedon the underside of elongated flat portion 41of retainer 15, the pad is normally biased downwardly to clamp scoresheet film 7 against a plate 42 secured toframe 11. Upwardly extendingportion 37 of the retainer is disposed at an angle to flat portion 41 toprovide a convenient hand-engaging surface to lift pad 40 by pivotingfiat portion 41 when it is desired to upwardly projecting embossment 44extending beside.

to FIGURES l, 3 and 7 embossment 44 functions to lift the end edge offilm 7 fed through guide slots 32 and '33, .when the film is moved tothe right as seen in FIGURE 3. It is to be noted that end web 45 of theframe is slightly beveled (FIGURE 7) to provide a sharp cutting end web45 of frame 11. As best visualized by referring edge 46 to facilitatecutting of the film by pulling the film upwardly when it is desired toseparate used film from unused film in the holder.

As best seen in FIGURE 1, writing table 2 is normally slanted in adirection toward the person who keeps score during team play. If theaxis of shaft 29 which supports film roll 30 were parallel with theplane of body portion 13, the axis of the roll would normally bedisposed at an angle to the horizontal. Such supporting of roll 30 at anangle has been found undesirable because the edges of the thin scoresheet film 7 frequently catch on-the inlet edges of guide slots 32, 33with corresponding tearing of the film while feeding. However, it is tobe noted with particularity that the axis of shaft 29 is disposed at anacute angle to the plane of frame 11 so that shaft 29 is horizontal whenthe film holder is mounted on the slanted table of the scoringprojector.

With reference to FIGURE 3, it can be seen that writing table 2 isprovided with conventional generally rectangular U-shaped recesses 47and 48 to normally accommodate ashtrays 49 and 50, for the convenienceof the bowlers. The film holder of this invention is mounted on thetable by first removing the ashtrays, whereupon the holder is positionedso that rear edges 51, 52 of end plates 25, 2 6 engage the inner centerwall 53 of recess 47 and the end edge of side plate 43 projects underashtray 50. When so disposed, the film holder is maintained in positionagainst accidental movement by the person keeping score, as well asothers who may accidentally touch score sheet holder 1.

With reference to FIGURES 3 and 4 it is apparent that score sheet filmholder 1 when mounted on writing table 2 has the under-surface of thematerial which forms the bottom wall of slots 32 and 33 in engagementwith the upper surface of glass plate 8. Since the sheet metal of frame11 is relatively thin, and since the score sheet film 7 is also verythin and flexible, the portion of the score sheet exposed at openings16, 17 normally rests against the upper surface of glass plate 8 topermit writing on the score sheet with apencil or other markinginstrument used by the scorekeeper. It is to be noted that the height ofscore sheet holder 1 isslightly less than the height of glass plate 8 toleave exposed marginal edge portions of the glass plate when the scoresheet holder is in position. The score sheet holder is so arranged whenin position, that openings 16 and 17 are disposed an equal distance fromthe center of glass plate 8. Since the center line of the optical systemof housing is normal to center web 34, it is apparent that inner edges18 of the frame material which defines openings 16, 17 are each the samedistance from the optical'system contained in housing 5. Likewise, outerside edges 19 are each the same distance from'the optical systemin thehousing 5. V

With reference to FIGURE 8, there is shown one embodiment of score sheetfilm 7 used with the holder of this invention. In this embodiment thescore sheet 7 has printed or otherwise applied thereto a bowling scoringgrid 54 comprised of a plurality of generally horizontal lines 55-60commonly referred to as player lines, and a plurality of vertical lines61 which define the various frames of a bowling game; It is to be notedwith particularity that player line 55 adjacent the top of the exposedportion of score sheet film'is parallel with top edge 62 of bothoepnings 16 and 17.- However, player line 60 adjacent the bottom of theexposed portion of score sheet film 7 is parallel with bottom edge 20 ofonly opening 16. The arrangement is such that the various player linesof a proper score sheet disposed in openings 16, if extended beyond'theright hand side edge of the table meet at a point which lies on line 55extended. Likewise, a proper score sheet disposed in opening 17 (notshown) has its player lines so arranged that if extended to the leftthese player lines also meet at a point lying along player line 55.

This slight convergence of the player lines in a direction away fromcenter web 34 alleviates the need for a truly aplan-atic projectionsystem, since the slight distortion at the sides of the image projectedonto screen 7' is compensated for by such convergence. As previouslystated such an arrangement is also more aesthetically pleasing than atruly rectangular grid where a pair of score sheets are in side by sideslightly spaced relation.

In the embodiment of FIGURE 9 the score sheet film is different fromthat of FIGURE 8. In this embodiment the score sheet film is cleartransparent film that is wholly. blank. Here, a bowling scoring grid 63identical to grid 54 is permanently associated-With glass plate 8 forexample, by etching the grid onto the under-surface of the glass, or byotherwise printing or affixing such a grid on the glass. The grid 63 foreach of the teams is disposed in such a position on the glass that it isimmediately beneath the respective openings 16 and 17 when holder 1 ismounted on the table. The advantage of this arrangement is thatunprinted readily available score sheet film can be used in place of themore expensive preprinted film shown in FIGURE 8.

FIGURES 10 and 11 show another variation relating to the use of a clearunprinted score sheet film. Here the bowling scoring grid 64 is on atransparent grid sheet 65 interposed between score sheet film 7 andglass plate 8 of the projector. Although transparent sheet 65 may beapplied directly to the top surface of the glass and temporarily securedthereto for example, with an adhesive, it is preferred to dimension thetransparent sheet to fit into guide slots 32 and 33 and to temporarilysecure the transparent sheet to the film holder. Then, during play, itis merely necessary to feed the clear unprinted score sheet film acrosstransparent sheet 65 until its appropriate faces are positioned inopenings 16 and 17, and scoring may then be done by -a scorekeeper usingthe indicia printed on the transparent sheet as a guide. As shown inFIGURE 11 sheet 65 is sufficiently flexible to engage the upper surfaceof glass plate 8 and thus provide a support for score sheet film 7 whena score is written on its surface.

When non-team bowlers are using the facilities of the bowling alleywhere the scoring projector 3 is located there is no need to project thevarious scores of the players for view :by an audience. Hence, a normalinexpensive opaque paper bowling score sheet is placed on writing table2 inany desired position. However, during team play a transparent scoresheet such as score sheet film 7 is necessary to properly project thescores of the various teams for view by an audience. The proprietor ofthe bowling alley provides each team with a score sheet holder 1 withthe magazine of the holder containing a roll 30 of'score sheet film. Itis merely necessary for a member of the team to remove ashtrays 49 and50, place score sheet holder 1 in position on the table with magazine 12extending into recess 47, and then replace the ashtrays to mount thescore sheet holder on the writing table 2. The scorekeeper can thenwrite the appropriate names of the players of the various teams in thespaces defined by the bowling scoring grid. At the end of a game it ismerely necessary for the scorekeeper to press down on portion 37-of filmretainer 15 to lift pad 40 away from the score sheet film. While pad 40is lifted the score sheet film is manually fed slightly to the right asviewed in FIGURE 3 whereupon embossment 44 lifts the side edge of thefilm so that it can be grasped by the scorekeeper. The used portion ofthe film is then pulled to the right as shown in FIGURE 2 until unusedfilm is properly positioned in the openings 16 and 17. Pressure onportion 37 is then released to again cause pad 40 to to sever the filmagainst cutting edge 46. As is apparent with reference to FIGURES 3 and4 a roll 30 comprised of a continuous strip of score sheet film isnormally stored in magazine 12. The film is fed between guide roller 31and the inner surface of leg 21 and then into guide slots 32 and 33.With the score sheet holder positioned on the scoring projector, thefilm engages wall 53 of recess 47 during feeding of the film. Wall 53functions as a guide to elevate the film to the approximate level ofguide slots 32 and 33.

In each of the several embodiments the score sheet film is atransparent, synthetic resinous film'for example, regenerated cellulousfilm, polyethylene terephthalate, polyvinylidene chloride, or cellulousacetate of uniform thickness of 2 to 5 mils (.002 to .005 inch). Withsome types of film the surface on which the score is to be written mustbe specially treated, in a well known manner to adapt the surface toreceive writing. However, a special pencil or pen may be used which willpermit writing on the surface of the film without such surfacetreatment.

Although a preferred embodiment of the score sheet film holder has beenshown and described-with a particular bowling scorer projector, andalthough several preferred types of score sheet film have also beenshown and described, it is to be understood that numerous variations andchanges can be made without departing from the scope of this inventionas defined in the appended claims.
